ANCHOR FOR TUBINGS FOR GAS-WELLS.

Specification of Letters Patent Patented Aug. 24, 1915.

Application filed August21, 1914. Serial N o. 857,866.

T0 all whom it may concern y Be it known that I, FRED J. MOSER, a citi-`zen of the United States, residing at Kane, in the county of McKeanandState of Pennsylvania, have invented new and useful Improvements inAnchors for Tubings for Gas- Wells, of which the following is aspecification.

This invention relates to improvements in `anchors for tubings for gaswells and conon the casing head.

In the present invention I provide a connecting device for the top ofthe tubing with the anchor devices thus making a positive anchor for thetubing which taken in connection with the connecting device makes acheaper and more effective construction.

The invention is illustrated in the accompanying drawings as followsFigure 1 shows a perspective view of the anchor T. Fig. 2 a section onthe lines 2 2 in Figs. 3 and 4. Fig. 3 an elevation of a casing headwith an anchor T on the tubing extending from the head, the anchor Tbeing secured by a casing clamp. Fig. 4 a similar view of a casing headwherein the anchor T is connected directly to the head.

1 marks the casing, 2 the tubing, 3 the casinghead, 4 the stung box onthe casing head through which the tubing extends and 5 a bottomconnection in the anchor T for the tubing. The anchor T also has a crossconnection 6 extending at right angles to the connection 5. Preferablythere is a cross connection 6 at each side of the tting as shown. Ahorizontal piping leads from the connection 6. Wings 7 extend outwardlyfrom the connections 5 and 6, the wings being formed integrally withsaid connections. These wings have the perforations 7*. Anchor bolts 8extend through these perforations andthrough the ears 9 on the clamp 10,the clamp 10 extending around the casing under the head 3. The wingsextend laterally beyond the periphery of the casing so that the bolts 8may be parallel to the axis of the tubing. In this way a straight pullmay be had on the bolts and the perforations in the wings and in theclamp may be vertical. This direction of the lperforations simplifiesthe manufacture. If desired the connection may be arranged verticallyextending from the top of the anchor T. A small connection 1l is shownon which is placed a pressure -gage l2.

In Fig. 4 Ythe construction is similar except that in place of the clamp10, the ears 13 are formed directly on the head and the anchor bolts 8extend through these ears.

The advantage of this anchor T, over the usual method of making theconnections to the top of gas wells, such as bolting twopart clamps tothe well tube 2 for anchoring the tubing and attaching the various f`lt,

tings for the gages and gas outlets, is that it dispenses with theclamps and all o f the fittings and forms a complete top connection forthe well wherein provision is made for all of the requirements. It is apermanent fixture and can be furnished at less expense and placed on thewell in less time than the usual clamps and fittings and it avoids theuse of the customary two-part clamp that is fastened together on thewell tube 2 withk small bolts that have been known to fail.

The design of the anchor T, may be varied to some other form of pipefittings having the wings for anchoring the tubing or casing in the welland I do not limit myself to the exact construction shown in thedrawings.

What I claim as new is 1. In an anchor for tubings for gas wells, thecombination of an anchor T, formed with a connection for the tubing, across Connection, and anchor wings extending from the T; a casing;anchor bolts extending from the wings; and means for connecting theanchor bolts with the casing.

2. In an anchor for tubings for gas wells, the combination of an anchorT, formed with a connection for the tubing, a cross connection, andanchor wings extending from the T, and having vertical perforatlonstherein; a casing; anchor bolts extendlng through said perforations; andmeans for connecting the anchor bolts with the casing.

3. An anchor T, for anchors for tubings for gas wells formed with aconnection for for gas Wells formed With a connection for the tubing; across connection; anchor'wngs extendlng from the T; and a Verticalconnection leading from the top of the anchor T.

5. In an anchor for tubings for gas Wells,

the combination of a casing; an anchor tting having a connection for thetubing; Wings extending from the tting laterally beyond the outerperiphery of the casing; and means actingl on the Wlngs for securing thefitting' to the casing. y

In testimony whereof, I have hereunto set-15 my hand in the presence oftwo subscribing Witnesses.
